Frequently Asked Heating and Air Conditioning Questions

When should I purchase a new air conditioning system?

Most home and business owners are currently using a unit that is more than 60% less efficient than today’s systems. Lack of maintenance will contribute heavily to the lifespan of a unit.

If you’re facing a big repair that isn’t worth the cost, it makes more sense to invest in a new system.

When your utility bills are increasing every month while your unit continues to perform less efficiently, it’s better to stop the bleeding and get a new unit installed rather than keep paying higher bills every month.

If you’re adding onto your home or facility you need to do an evaluation of your AC unit’s capabilities, you may need to expand your system.

How do I know what size AC unit to buy?

This question has to be answered on a case by case basis because there are just so many variables involved. It depends upon your home’s age, square footage, construction type, and insulation type, as well as the performance rating of the system you choose. With decades of combined experience, the experts at Lakeside Air can custom-tailor your system to your home’s exact needs.

What is an Energy Star rating?

You may have noticed the ENERGY STAR symbol on some of your appliances, including your furnace and AC unit. HVAC systems that have the ENERGY STAR symbol meet stringent energy efficiency guidelines set forth by the Environmental Protection Agency and the Department of Energy, and are designed to be more eco-friendly than comparable products.

How can I protect my HVAC investment?

Without a doubt, scheduling regular maintenance inspections is the best way to get the most out of your new system.

How often should I have my heating and cooling units serviced?

Lakeside Air recommends servicing your system twice per year to ensure that systems are performing safely and efficiently. When airflow gets restricted by the buildup of dirt and debris, systems require much more repairs. Proper HVAC maintenance improves the efficiency and lifespan of your equipment.

Why is my AC unit freezing up?

There are a few possibilities that can cause your AC unit to freeze up; most of them usually need to be repaired by a professional technician.

Low refrigerant: In some cases, freezing up is initiated by a leak in the refrigerant lines. Weak solder joints, friction from piping rubbing or vibrating against an object, leaking valves or loose fittings can cause leaks.

Dirty evaporator coil: Over time, the evaporator coil will become dirty. On these occasions, the results are similar to those of having a dirty filter. Over time you will lose airflow, slowly enough that you probably would not realize it until it freezes up or is not cooling adequately.

Defective blower motor or relay: A blower motor running at an incorrect speed or not running at all can cause freezing. It can also be sporadic, starting at full speed and slowing down after it heats up.

How do I know if there is an existing warranty on my HVAC system?

Locate the label on the outer surface of the equipment for a manufacture date. If the equipment is less than five years old it may have a warranty, but also may not depending on which model you own. Warranty terms and conditions vary by manufacturer and the installing company. Our staff at Lakeside Air can verify the warranty status of your heating and cooling system.
